ESP32Sx01: common questions
What microcontroller does the ESP32Sx01 use?
The ESP32Sx01 is built around the ESP32-S3-MINI-1, from the ESP32 family.
How big is the ESP32Sx01 PCB?
The ESP32Sx01 measures 60.5 × 50.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP32Sx01?
33 components, from 21 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the ESP32Sx01 design files?
From the mlab-modules/ESP32Sx01 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the ESP32Sx01 design in my own project?
The repository has no license, so all rights stay with mlab-modules. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESP32Sx01 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
